- Application filed November 4, 1905. Serial No. 285,879. I

Toallwhom it may concern:

.Be it known that 1, CHARLES ULMER, a

citizen of the United States, residing at Lisbon, in the county of Ransom and State of North Dakota, have invented a new and useful Change-Making Machine, of which the following is aspecification.

This invention relates to change making machines, and has for one of its objects to provide a machine in which change to any amount within a redetermined limit may be 'delivered with t e utmost accuracy, pro vision being made for receiving or depositing money or checks of anyvalue, whether the latter be in the form of even dollars, or representing fractional parts of dollars, and for deducting therefrom-the amount of the purchase and delivering the exact change.

A further object of the invention 1s to'provide a machine of this character in which the character of the change delivered is optional with, the operator, that is to say, either bills 7 other or coin, or both may be delivered from the machine, as desired. a

With these and other objects in view, as will more fully hereinafter a pear, the invention consists in certain novel eatures of construction-and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being-understood that various changes in the form, proportions, size and minor details of the struc- Iture may be made without departing from the spirit orsacrificing any of the advantages of the invention.

Similar numerals of. reference are emplbyed to indicate corresponding. parts throughout the several figures of the drawings.

The machine forming the subject of the present invention is designed for the desecured.

very of change in amounts of less than ten dollars, but the capacity of the machine may be altered to accommodate any amounts,

and whilein the present instance certain of the parts are referredto as dollar slides or dollar mechanism, and other parts as freetional currency or cents slides or delivery mechanism, it is to be understoodthat these may represent the monetary system of any country. b

The working parts of the machine are arranged within a suitable casing 40 and are supported by a frame which includes a base 41 to which the lower edge of the casing is The machine generally is divided into two sets of mechanisms, one for the selection and discharge of even dollars, and the other for the selection and "discharge of fractional parts of dollars, that is to say, the mechan- ISIII at the lower part of Fig. 1 and the right of Fi 2 controls the selection andidischarge of; do lar's, or multiples thereof from the machine, while that portion of the mechanism at the upper 'part of Fig. 1, and to the left of Fig; 3, controls the discharge'of fractional currency. '1

senti I I and the keys 44 representing amounts from All of the parts are operated from the front of the machine (Fig. 4),-the selecting ward the rig t, and the actual operation of delivering the change being effected by a being accom lished by banks of keys tohandled crank-"42 wh ch receives first a practically complete rotation clockwise, and then a practically complete rotation in the reverse direction.

The keys, for convenience, are separated into groups, the groups 43 and 44 bein operated to correspond to the amount 0 deposit or amount received, the keys 43 repre- T dollars from two to ten, inclusive,

ten cents'to-one dollar in multiples of five. The oups of ke s 45 and 46 are operated in accordance wit the amount of purchase, the group 45 representing dollars from one to nine inclusive, and the keys 46 fractional currency from five cents to ninety-five cents in multiples of fives 1 -As the United States monetary system does not now include any coin between a cent and anickel, it is' unnecessary to make any provision for the deposit or receipt. of a As the purchase amount may.

nickel or less. be less than a nickel, another bank of keys 47 is arranged at the top of the machine, these keys being four in number and representingpurchase values of one, two, three and four cents, respectively,

In using the machine, the deposit keys 43 and 44 are operated in accordance with the amount deposited, for instance, four dollars and fifty cents, which would require the deression of the key 4 of the bank 43, and the ey 50v of the bank 44. The purchase keys are then operated, and if the purchase be four dollars and forty-six cents, the key 4 of the bank 45, the key 45 of the bank 46, and the key 1 of the-bank 47 will be de ressed. The crank 42 would then be turne clock- .wise to an extent of about three hundred and fifty degrees, and thence backagain to its original position, this operation causing the delivery of' the change, four cents,'at the opening 50. I

The only. additional mechanism to be operated from the. outside of the machine is a key 51, immediately above the bank 44, this key being depressed when it is desired to deliver paper money instead of coin. When this key is out, silver dollars to the number of four may be delivered, in change less than five dollars, or a five dollar note, or a gold ieceand four silver dollars, but if the key is depressed, the machine will deliver dollar notes in place of silver dollars.

. Within the casing is arranged a frame ineluding two sets of vertically disposed angle .Eachset of bars 52 and 53 constitutes a guide for a slide carryln box, there being two of such boxes, 56 an 57, theformer for the rece tion of selecting slides which convertical guide bars, and the boxes as a whole less is tendered for purchase.

being of generally'rectangular contour, and their inner vertical faces being provided with a plurality of horizontally disposed parallel grooves 59, said grooves being arranged in airs and adapted for the reception of the seecting slides 60. In the box 56 are arranged nineteen pairs of grooves for the reception ofnineteen slides 60 that'oontrol the discharge of amounts from five cents to.-

ninety-five cents, in multiples of five, while in the box 57 are nine pairs of grooves for the reception of selecting slides controlling the delivery-of even dollars from one to nine inelusive, and anadditional set of grooves for the reception of a blank slide which prevents the delivery of any dollars where a dollar or (Fig. 7). The particular construction and arrangement of these slides will behereinafter described.

At one side of the frame members is apair df vertically disposed guide bars 61, the lower ends of which are secured to the base 41, (Fig. 5) while the upper ends are rigidly secured to the bracket 62, projecting from the upper frame member 54. These bars serve as guides for a vertically movable weight 63, to the top of which is secured a sheave 64, and over the sheave passes a flexible cable or chain that is guided over suit able sheaves 66, supported by the frame, and has its opposite ends secured, respectively, to the boxes 56 and .57, and the weight is greater than the weight of the two boxes and the slides carried thereb so that if left free, the weight will descen and the boxes-will move to the to of thefraine. In the normal position of t e parts, however, the weight 63 is heldat the highest point, as shown in Fig. 2, by means of an arm 68', one end of which engages under the weight, while the oppositeend is pivoted to a pin 69 carried by a bracket 70 rising from the base plate. The lower face of this-arm-is engaged by a pin or antifrietion roller 71 carried by a rocker arm 72 that is secured to the main operating shaft 73 of the machine, said shaft being journaled n suitable'bearings that are carried by a frame 74, (Figs. 2 and 5) and being provided at its outeren'd with the operating crank 42. The handle 75 of this crank carries a spring pressed bolt 76 that is normally forced into a cient to hold the crank and rocker arm 72 in proper position and to maintain the arm 68 and the weight 63 in the elevated position.

As before described, the crank arm '42 receives aclockwise movement at first, being 70 the movement indicated by the arrow in Fig. 2, and this ermits gradual lowering of the arm 68 and allows the weight to descend, this constituting the first-portion of the selecting operation. the pin orv anti-friction roller-72 is allowed to pass through a suitable groove 78, formed near the pivotedend'of the lever 68.

Referring now to Figs. 23 to 28, inclusive, 60 indicates the fractional currency se- 80 lecting slides, there being nineteen of such slides in the box 56, and said slides are provided with openings the arrangement and number of which is governed by the amount of change under. the control of the slide.

Fig. 23 represents the' five cent slide, this having a single opening to permit the delivery of five cents only, and this slide isarranged in next to the uppermost groove 59 of The second slide, shown in Fig.

the box. 24, controls th'e delivery of both five cents and ten cents, and is arranged immediately below the five cent slide. The third slide, shown in Fig. 25, contrbls 'the deliveryof five cents, ten cents and'fifteeh cents.

Fig. 28 represents the lowermost slide in the box,,and this slide has under itscontrol; the delivery of amounts from five centst ninetyfive: cents in multiples of five, the

slide immediately above it, represented in I00 Fig. 27, controls the delivery of amounts from five cents to ninety-cents in multiples of five, and the third slide from the bottom, being that shown in Fig. 26, controls the delivery of change fromfive cents to eighty five cents in multiples of .'five, and so on throughout the entire series of slides.

a The general arrangement or system of placing the openings in the slides will be evident on an inspection of these figures. The I :o openings are divided into five rows, extendinglongitudinally of the slides, and parallel with each other, the row nearestone edge controlling the delivery of nickels, the next row the delivery of dimes; the, next row-the r 15 delivery of two dimes; the next row the delivery of quarter dollars, and the final row the delivery of half-dollars. The -arrange-' ment of "the openings in these'rowsis governed by the position of members actuated 1'20 by the de osit and purchase keys.

Each side 60 is formed of a thin strip of metal the front nnd of which may be sliglftly narrowed while'i'lit the rear end is an opening 80 for the reception of a slide means, hereinafter described.

The arrangement of the dollar slide 60 (Fig. '36) is exactly the same, except that suitable recess 77 in the front of the casing, there are nine selecting slides only in the box the connection between thetwo being sufiil 57. This box also carries an additional Ego After further movement, 7 5

actuating 1 z 5' l blank slide which acts to prevent the deliv-.

ery of dollars in cases where one dollar or less is tendered for urchase. The first and upper'most of the ollar slides has a single openmg to permit the delivery of one dollar; the second has three openings to ermit the deliver of one dollar, or of two ollars, and the thir and fourth havin openings to ermit the delivery of three do ars and four ollars,

respectively. The fifth slide has a single opening to permit the delivery of a five dol ar b111, or five dollar gold piece and has, also, openings for the deliver of, one or two, or t me, or four dollars. he openings of the remaining slide are arran ed on the same principle, so that the nint slide, (Fig. 36) lein the slide of highest value, will control t e inclusive.

When the slide carrying boxes are allowed. to ascend by the lowering of the operating lever or arm 68, they move upward for a dis-.

' tance determined by the deposit keys, and

the greater the amount deposited, the further the boxes travel.

In case a dollar or less is tendered for purchase and none .of the keys ofthe bank 43 is de ressed, the box will move upward the full distance or until the lowermost blank slide ,finger iece85, on which is marked the value of the ey, thatis 5, 10, 15, etc., and a shank 86, the latter being guided in three alining openings, .18 and 19) one of which, 87, is formed in" t e outer casing, a second, 88, in one of'the guides 52, and a third opening,

. 89, is formed in an outer guard plate or auxiliary casing 90, that is carried by the main casing, and normally these keys are held outward to the position shown in full lines in Fig. 19 by means of helical compression springs 91. When depressed they are moved I to the dotted line position and are projected 'in the casing.

beyond the inner face of the guide strip 52 to form a stop for limiting the extent of u ward movement of, the box 56, as will e clearly seen on reference to Fig. 29.

Arranged within the auxiliary casing is a locking strip 92, that is guided by headed pins 93 carried, by the strip and projecting through vertically disposed slots 94 formed v This strip is normally held in elevated position by a compression spring 95 arranged between the lower end of the strip and a fixed bracket or lug 96 projecting from the casing. The opposite edges of the strip are inclined, and present or forni stops with which may; engage shoulders 97 formed on the inner sides of the shanks 86, so that when the keys arepushed inward, the shoulders will pass beyond the inner face of the strip elivery of even. dollars from one to nine operation.

. segue and will be caught and held in the position to which they are adjusted. In this connection it is to be observed that as the shanks shanks. inward, that is, to move the shanks shown in Fig. 19 toward each other, in order to insure the locking of the shoulders 97 against the inner face of the strip, and when a key is once depressed, its. shank will remain inposition to stop the upward movement of i the strip carrying box, until allof the parts have operated, and the change has-bee11 delivered.

Projecting from the lower end of the strip '92 is a bracket'99 having a pendant armIOO,

and pivoted to the outer end of the'bracket is. a bell crank lever 101, the approximately vertical arm of which receives the thrust of a spring 102, placed between the arm and the pendant arm 100. The horizontal arm of I the bell crank lever is disposed in the path of a lug 103, projecting from the side of the box 56, and as the box moves upward, the .lu will engage the horizontal arm of the bell crank lever and will idly swing the same as it pushes past it without effecting any move ment of the strip '92. On downward movement, however, the swinging of the bell crank lever is resisted bythe s ring-102, and

said bell crank lever, toget er with the bracket 99 and the strip 92, will be carried down against the stress of the spring 95,;

until recesses 104 formed in the opposite edgesof the strip arrive in alinement with;

the key shanks, whereupon the springs 91 of the keys force the latter out t. initial position, and the parts are ready for another After the strip has been moved down to its fullest extent, the spring102'will yield and the pawl 103 will click past the bell crank lever until it is again below the: same and in readiness for another operation:

The extent of movement of the box 57 which carries the dollar selecting strips is best shown in Figs. 10 and 11. In this case the bank of keys 43 are operated in order to project a pin or stop into the path of move ment of the box 57, and each of the keys is provided with a shank member 106 that extends horizontally across the machine and is connected to the outer end of a lever 107,

there being nine of such levers, as shown in Fig. 10.. i

Secured to one of the guide strips 53, and slightly spaced therefrom, is a strip 108 (Figs. 10 and 11 to which are secured a plurality of brackets 109, serving as supports for a verticallydisposed pin 110, on which the levers 107- are independently pivoted. The inner end of each lever is connected to a pin 1 11 which extends through guiding openings in the angle bar 53 and the strip 108, and normally is held in ,the' full line position shown in Fig. 11 by a helical compression spring 112. When akey is depressed, the parts move to the dotted line position shown in Fig. 11, and the inner end of the pin is projected beyond the inner face of the bar-53 into a position in the path of upward move ment-of the box 57, this forming the-deposit key means for controlling the extent of upward movement of the dollar slide box.

Projecting fromthe upper bracket 109 is an-arm 113, and from the lower bracket projects an arm 114. To this latter arm is pivoted the lower end of a bar 115 the upper end of which is guided by the arm 113, the

extreme upper end of said bar being pivotallyconnected to a'rod 116, passing through a suitable guiding lu 1 17 tcarried by the strip 108, and normal-lyield in the position shown in Fig. 10 by means of a spring 118. One edge of the bar 115 is bevelled and is adapted "to be engaged by catches 119, projecting from the evers 107, and when any lever is operated, that is, moved to the dotted line position of Fig. 11 this catch willride on the inclined edge of the bartllS, and, assing over the outer face of the bar, wil be locked in such dotted line position in order to hold the stop pin 111 in a ositik'i n to limit the upward movement of t e box 57. The outer end of the rod 116 carries a bell crank lever 121, the vertical arm of which is weighted to maintain the lever normally in the position showninFig. 10, and said arm is provided with a stop lug 122 to prevent movement of the bell crank lever in one direction, .but 5 leaving it free to swing in the opposite direction.

Securedto the wei ht .63 is a sleeve 123, that embraces oneof t e guide rods 61, and is provided with a cam 124, which, as the weight moves downward, during corresponding upward movement of the box 57, will strike the horizontal arm of thebellcrank lever, and the latter will swing freely on its pivot, without affecting the position of the rod 116. When the weight ascends, at the completion of a change making operation, and while the box 57 is seeking the initial lowermost position, the cam 124 will engage against the horizontal arm of the bell crank lever and will move the latter in ing movement being prevented by the lu 122, and, as a result, the rod 116 will be move in the direction of its length, and the locking strip will be forced outward in order to free any one of the catches 119 which may have engaged .with the locking strip. The pins 111 control the exent of upward movement of the box 57 which carries the dollar selecting slides and determines the slide -to be subsequently moved in selecting the amount or money to be delivered from the machine.

In the event of a dollar or less being tenslide.

ard, swing 43 will be depressed, and the box 57 will thereupon move to the highest position presenting the lowermost or blank slide in position for further movement, this blank slide servin to prevent the delivery of any money from t e dollar or five dollar magazines.

The frame 74, hereinbefore referred to, is rovided with a pair of spaced arallel and orizontally disposed bars 126, (l! igs. 2, 6 and 9) each of which is grooved for its entire length, and the walls of the grooves are under cut for the reception of two slides 127 and 128 that are adapted, respectively, to engage and o erate the fractional currency and dollar se ecting slides, At the outer end of each slide bar is secured a spring-catch 129, that normally is held in elevated'position by a lug 130, secured to the bottom-ofthe spring and bearing on the lower wall of the groove, but at the extreme end of the groove is arranged a notch 131, (Fig. 6) into which the lug rides and permits downward movement of the catch, so that the latter mayenter the opening 80 of any slide which at the time is in position to be engaged, it being observed that the rear ends of all of the slides are arranged in a vertical plane close'to the inner ends of the bars 126, and immediately after At the rear end of each operating slide is a rib 132, that is provided with a'notch 133 adapted to receive a pivotally mounted. spring pressed catch 134, (Fig. 5-) there being an independent catch for each operating These catches are pivoted to a slidable block 135 that is mounted on the guide bars 126, the opposite sides of the block having pendant flanges that are rooved for the reception of the side walls of said bars, and from the uppercentral portion of the block extends a projection l37for a purpose hereinafter described.

The main shaft 73. is provided with a sprocket wheel 139, (Fig. 5) and the frame has bearings for a transverse shaft carrying a sprocket or guide wheel 141. Around these two wheels passes a link belt 142, the o posite ends of which are, secured to the blbck 135, and when the shaft 73 is turned in the proper direction, the block will be moved forward in the direction indicated by the arrow in Fig. 5. During the movement from the full line tothe dotted line position shown in Fig. 5, the catches 134 will ride on top of the ribs 132, and no movement of the operating slides will occur, this idle move-' ment being for the purpose of allowing the weight to descend, and as soon as the latter has been lowered, the further forward movement of the block will cause the catches 134- nection withone of the pins.

' to enter the recesses 133 of'ribs 132, and the slides will then be carried along with the block. During the first ortion of the movement, the catches 129 w' engage in the open- 3 ings' 80 of any selecting slides which have been adjusted to position-by the operation of the" deposit keys, and said slides will be \carried forward to an extent determined by adjustment of the purchase-keys, The ex- 1o tent of movement of the selecting slide is, of

course, variable, and in'order to permit this, while obtaining a full stroke of the block 1.35, the spring pressed catches 134 come into play. When the resistance to the forward movement of the slide is suddenly increased by stoppage of said slide, the spring catch rides out of the recess 133- and over the end of they rib'132, thence sliding -over the face of the operating slide for any required distance, so that there is n o-danger' of breakage, and perfect action under all possible selecting I movements of the slides is provided for.

. Near the completion of the forward movement of the block 135, the lug 137 will engage'against the end of a horizontallyslidable bar 145, (Figs. 2 and 5) and will move the latter against the stress of a spring 146 fromthe osition shown in full lines to the position s own in dotted lines, Fig. 5, this ar serving to transmit movement to the "mechanism by which the money is delivered from the containing receptacles, as will be hereinafter described. v

On the return movement of the main operating crank and shaft 73, the first effect of the movement will be to,allow spring 146 to move the bar from the dotted line to the full line position, the o eratingslides-127 128 will withdraw the se ecting slides .60'60 0 until the lugs 130, riding against the inclined walls of recesses 131, will disengage catches 129 from the openings 80, and on further movement the catches 134 will ride out of the recesses or notches 133 of ribs 132, and the 45 box operating weight 63 will be elevated as previously described.

Near the delivery end of the machine is a frame (Figs. 2 .and 3) that forms a support for two parallel horizontally disposed 5o ars 151 and 152, the upper faces of which are provided With grooves for the reception of the selecting slides, the latter being moved through said grooves in the direction of the length of the bars by the mechanism previ- 5'5 ously described, and. the slides are held from upward movement by cover plates or strips k1,53, secured to the edge flanges 154 of said ars. l 1

The bar 151 is'provided with a centrally 69 disposed row of alining o enings for the reception of stop pins 155 of a number equal to the number of keys of the bank 46, there being nineteenof'such keys in the present instance, and each having an inde endent conto suitab amount involvin sea y is end of each lever is a shoulder 159 which engages with a locking strip 160, hereinafter described, the function of the strip being to So look any key in depressed position.

Each of the ke s 46 has a shank member,

160 (Fi s. ,3 and -ZQ) "that is uided in an opening ormed in the horizonta portion 161 of the casing, and. the lower portion' of the 8 5 shank is provided with an elongated eye 162 that embraces the lever 1 57, and below the eye is a finger 163 arranged to engage with a rod 164 extending across the full widthof the keyboard. Inpracticetwo rods 164 are em- 0 ployed in order to accommodate the two rows of keys of the bank 46, and both rods are rigidl connected to the approximately horizonta arms of the bell crank levers" 16 6' that are'fulcrumed on pins 167 carried by the casing. The opposite arms of the bell cranklever engage with the opposite arms of an.

advance pin slide 168 (Figs: 2 and 3') adapted e guides 169 in the frame 150, and V normally held depressed by a spring.1'70. on The function of this slide to prevent the delivery of an excessive amount from the dollar reservoirs mcases where the change to be delivered is less than a dollar, or any fractions of a dollarfas hereinafter more lly described.

. The bar 152 is provided with a centrally disposed row of openin s' 172'for the reception of vertically movable pins 173, of a number equal to the number of purchase keys in the bank 45, there bein nine of-such keys in the present instance. larch pin'is supported by a lever 174 pivoted on a horizontally disosed shaft 175 that is supported by the i I 'rame. The outer or rear end of each lever '1 r 5 is connected, to a spring-177, hung from a bracket 178, and tending to maintain the lever in elevated position with tne'sto pin depressed. Each lever isconnectedy arod 179 to one of the keys of thebank 45, and when any one of such ke s is depressed, its correspondin pin 173 wil be elevatedhnto the path of t e dollar selectin slide, the extent ofmovement of such sli e being deter mined by the position of the pin, and when 1 z 5' the lever is operated, its outer end will be caught andfheld by a locking strip 180, so that the pin will be maintained infelevated position after the removal of the finger from the key (Figs. 3-and 35.)

In the construction as thus far described, it will be seen that the operator Ina depress any of the purchase keys of the dollar bank to elevate an lpin 173 into the path of movement of the ar selecting slide, and in similar manner may depress any purchase key in the fractional currency bank 46, and elevate.

any one of the stops pin 155 to adjust or limit the extent of movement of the fractional currency selecting slide.

In many cases 1t is necessary to split up a dollar in order that proper change may be made, for instance, if five dollars is deposited and the amount of purchase be three dollars and fifty'cents, the machine must deliver one dollar and fifty cents chan e. l The operator depresses first the five dol ar key of the deposit bank, and then the three dollar key and fifty cent key of the purchase bank. Or-

dinarily the operation of the three dollar keyof the purchase bank would move one of the pins 173 to a position to stop the selecting slide in such manner that, owing in part to the revious selectin movement of'the deposit ey, the dollar si e of the machine would deliver two dollars change, and on the fractional currency side the depression of the fifty cent purchase key, to ether with the depression of v a ke of the do] ar bank on the deposit side woud cause the delivery of fifty cents in fractional currency, so that the machine would then deliver two dollars and fifty cents, or one dollar in excess of the proper amount. To correct this it becomes necessary to provide for the stopping of the dollar selecting slide inadvance of the position to which it would ordinarily move when the.

three dollar key of the purchase side is depressed and a fractional currency key of the purchase side is alsodepressed. To explain this more fully, if the amount of deposit be five dollars, and the purchase three dollars, it

I is not necessary to further control the movement of the dollar selecting slide, and the machine "delivers two dollars change, but where the purchase is three dollars and a fraction of a dollar, the operation of the fractionalcurrency keys of the purchase side 'jecting pin 183, and the opposite side with a recess 184, the pin of one lever entering the recess of the next adjacent lever representing the next highest value, that is to say, thepin carried by the seven dollar lever will enter the recess of the eight dollar lever, and the pin of the eight dollar lever will enter the recess of the nine dollar lever; The arrangement ofthe recesses, however, with respect to the pins is such that on the depression of any keyof the dollar bank, its corresponding lever will be freely moved to project the-pin 173 the roper distance without causing the lateral y. projecting pin 183 to engage with the wall of the recess 184, and this first movement brings the rear end of the lever to the dotted line position a of Figs. 3 and 22, the end of the lever entering a recess 186, i'n the locking strip 180, while the tongue 182 is moved from'aposition to one side of the plane of movement of, the advance pin slide 168, to a position in the path of movement of v such slide, all of the remaining levers of the bank remaining in the full line position shown in Figs. 3 and 22, and the parts is'further illustrated in ig. 20, wherein the first lever 174 is shown as projecting its pin 173 into the path of movement of the seecting slide, while the remaining lovers are in normal position.

osition of the,

The key of the dollar bank, in the resent 4 instance the key three, for example, aving been depressed, the fractional. currency key fifty of the bank 46 is depressed,- and in moving down, the tongue at the IWII' end of its corresponding lever 157 engages in anotch188 in the locking strip 160, while the pin of this lever is adjusted into the path of movement .of the fractional currency selecting slide, as will be seen on reference to Fig. 29;

This initial downward movement moves the lever to the dotted line position 0 of Fig. 3,

and the tongue163 of the key shank, engaging cross bar 164, depresses the same, and

the movement is transmitted to thebell crank lever 1'66, and from thence tothe advance (pin slide 168, the latter beingiforced upwar in the direction of the arrow, Figs. 3 and 22, and its beveled upper edge engaging the three dollar lever whic has been moved to the dotted line position a and moving said lever'further u ward, or to the dotted line position b of ig. 22. During the initial movement of the three dollar lever, its pin 183 is moved upward in the slot 184 of the four dollar lever, until it is nearly in contact with the 'wallof. the slot. The further upward movement of said three dollarlever, a

from the position a to the position b causes pin 183 of the three dollar lever to engage against thewall of the slot 184 of the four dollar lever and move said four dollarlever upward, carrying with it the in 173 of the four dollar lever, so that the se ecting slide is stopped, not by the pin of the three dollar lever, but by the pin of the four dollar lever,

as will be evident on reference to Fig. 21, and this revents the delivery of two dollar from the ollar magazine, only a single dollar being delivered therefrom, and in every case where a fractional currency key is depressed,
